Does the Laird FTP firmware upgrade daemon in WB45 have the ACK system when the firmware upgrade is done?

Answer

The FTP firmware upgrade daemon will send notifications with the firmware update status to UDP server port 2012. This is sent as a UDP datagram and XML formatted with: ethaddr, fw-build-version, status-word, and an optional message.

The status text is one of the following: update_success,  update_pending,  update_failure, update_error

Following the re-flashing of all images on the WB, an "update_pending" is sent back to the server. Upon reboot of the pending WB update, a platform init-script processes any updated settings. If the update is successful and the WB rebooted correctly, then the text “update_success” is sent to the server.
